IMPROVLD ADJUSTABLE. sol-"Ap f TO ALL WHOM IT MAY CONGERN: Y y

Be it known that- I,EDwAnD D Erz, of Philadelphia, Pennsylyania, have invented an Adjustable Sofa;4

and I do hereby declare the following to be a full, clear, and exact description of the same. i

' My invention consists of certain devices, fully described hereafter, whereby the hack of a sofa may be turned to and maintained at any desired inclination, or -in a position level'with that ofthe body. 4

In'order to enable others to make nuduse my invention, I will now proceed to describe Reconstruction and4 operation, reference being had to the accompanying drawing, which forms a .partcf this specification, andi in which- Figure l is an end view of my improved sofa, i

Figure 2, a transverse section,

Figure 3, a rea-r view, andl 4 Figures 4 and' 5 detached views drawn to an enlarged scale.

The body of the sofa consists of two end-frames supported-on legs in the usual manner, sind connected together by longitudinal strips, upon which rests a detachable cushion.

A, iig,r1, represents one of the end-frames, 'the rear of which is rounded, as shown, so as toform a bearing, onwhichone of the end-frames, B, of the buck ofthe sofa can rest and turn.

In the upper surface of the rounded rer portions ofthe end-frames A are any suitable number o'f notches a a, for a purpose described hereafter. 4 v l To each end-frame B is attached an arm, c, (figs, 1 and 2,) which'fprojects some distance below the saidI frames, und is hinged by apin, 9;,'to the end-frame ofthe body. i I

The inside of each of the'endframes' B of the back is recessed vfor the reception ,cfa spring-bolt, d, contained and operating within a casing,' H, and lthe latch-head of which projects below the said end-frames B, and into the notches a a of the rounded renr portion of the end-frames A ot` thebody, as shown in the enlarged view, fig. 5.

4FromA these notches the springbolts d muy be withdrawn by the operation of a spring-lever, e, (figs. 4 and`5i) At two points in a longitudinal stay; 7L, at the rear otlthe sofa,.are cut slots," within'which are hung'small grooved pulleys, lo the outer end of each of-the levers e is connected one endlof a cord, l, these cords passing under and around the pulleysjj, and thence upward through a hole inthe top rail hof the back, where they are connected. By ineans cfa tasse! or other suitable-'attachment to these coi-,ils at their outer connected ends, they may be simultaneously pulled, and so caused `to operate the levers e c as to draw the spring-bolts d fromthe notches a ofthe rounded rearportions ofA the end-frames A.

When it'is desired to change the inclination of the hack of the sofa, or tofornrabcdstead, all that is necessary is to pull the cords Z l, thus withdrawing the bolts d from those of the notches a, in which they may he fitting. rihe end-frames B of the hack may then be 'turned upon therounded rear portions-of the end-frames A of the body, u'ntil they assume the desired inclination or position, in which they will be secured upon releasin'fr the cords Zland levers e c, thereby'allowing the spring-bolts d te project into those of the notches a,`to

D which they may be opposite. l

To the rear of the end-.frames B of the back are hinged legs.m"m,for the support of the back when turned to a, level withthe body, so as to form bedste'ad.l These legs;V when not in' use, arerfolded against the rear'cf the back, and nre secured in either position by hooked rods adapted to staples on the rear of the s cfa, as shown in lig, 3.. f

"I elainl usamy invention, and desire to'secure by Letters Patent-#- i l. The rounded and notched rear portion of the lendif-rame A of the sofa, in 'combination with the endframes of the hack, hinged to the body, and provided with spring-bolts adapted to theA notches on the said roundedportions of the frames A, all Yas set forth for thc-purpose specified. 2. I claim the above,`in combination with the within-described cords and pulleys, by which the spring-bolts at the opposite ends of the sofa may be operated simultaneously, -as described.l 'i l 'l l i i In testimony whereof, I have signed my nameto' this specication in the presence lofftwo subscribing witnesses.
